Solved Level not loading

I am trying to use teleport with the constructor Position and also tried $level->getSafeSpawn() but I think the level is not loaded because it teleports to the same level you are on. This happened in different servers I tested and if it doesn't work on multiple servers it might be a pocketmine bug. I also tried $server->getLevelByName("world2")->getName() and it crashes with the error of "Call to a member function getName() on null"

So anyone know a fix to this or how to load levels better, or is there a better way to teleport to multiples levels?

just look at multiword plugin

Like... What?

ManyWorlds is a good plugin for teleporting between worlds)))

PHP:

//onEnable 
$this->getServer()->loadLevel($level);
//
$player->teleport(new Position($x,$y$z,$this->getServer()->getLevelByName($level));

teleport to Default spawn

PHP:

$player->teleport($this->getServer()->getDefaultLevel()->getSafeSpawn());

Both don't work, already tried.

Try loading level/s on enable.

PHP:

public function OnEnable()
{
# I suppose it's more than 1 level.
$to_load = ["Level Name","Level Name 2" /* ... */];
# You can get the server by folder name, but in this case I'll get it by the level name.
foreach($to_load /* levels */ as $level){
$level = $this->getServer()->getLevelByName($level);
$this->getServer()->loadLevel($level);
}
# Now all levels inside $to_load are loaded.
}

I've figured out that some levels are corrupted and they won't load so I have to generate new ones.
